Excavator in mountainous plateau characteristics Caution use of construction machinery in the mountainous plateau during the construction is: because of the terrain is high, thin air, the engine power down, for construction machinery steering and braking can have some adverse effects, we must take certain technical measures to strengthen the maintenance and upkeep. Effect of Plateau Mountain construction machinery work with increasing altitude, atmospheric pressure and air density has declined, so reducing the amount of engine inflatable, reducing the engine output. In exceptional circumstances, the high temperature on the plateau of the engine power may be reduced by 40% to 50%. Due to the thin air, can not guarantee the normal fuel mixture ratio, due to incomplete combustion caused by a cylinder, a piston and valve, etc. appear coke and gumming too quickly, increasing the wear of these parts. Low pressure plateau boiling point of water will reduce small excavators offer, at an altitude of kilometers boiling point of water is only 86.8 ℃, thus making the engine cooling water consumption increases. Thin air compressor will cause reduced productivity, so that the reliability of pneumatic brake mechanism deteriorates. Influence 泰安嘉 and Heavy Machinery Co., Ltd. hypothermia on the excavator cryogenic engine start difficult, mainly because of the battery decreased ability to work, increasing the viscosity of the lubricant and fuel atomization bad. The battery at low temperatures, the viscosity of the electrolyte increases, penetration decline, so that the battery capacity increases the internal resistance and terminal voltage decreased significantly, not even discharge. Voltage drop so that the output power of the starter not required, it is difficult to reach the starting speed requirements. The viscosity of the oil increases as the temperature decreases, flow properties are deteriorated, so that the engine lubrication conditions deteriorate, the crankshaft rotational resistance increases. Due to the low temperature starting the engine crankshaft speed is not high, the intake pipe temperature and gas flow rates are low mini excavators, poor fuel atomization quality, further increasing the difficulty for starting the engine. At low temperatures, the viscosity of the oil in a large variety of poor mobility, to the operation of the roller makes it difficult, and exacerbated the mechanical wear and tear. Viscosity oil is large, increase the power loss mechanism churning operation, and the engine power down, low transmission efficiency, thereby reducing the driving ability to walk and exciting roller bodies. Lubricants illiquid small and medium excavators, to lubricate certain components added to the difficulties, reduced lubricating effect, thereby increasing the mechanical wear of engine and transmission parts. Large-viscosity oil, also increased pipeline resistance, the hydraulic steering difficulties, hydraulic system performance degradation mini excavator factory direct, drive brake performance deteriorates to increase the difficulty of the road, safe driving adversely affected. In the cold season, there is widespread freezing construction hazards, such as: battery electrolyte will freeze them to halt work; a water-cooled engine cooling water freezes Donglie radiator and cylinder block.泰安嘉 and Heavy Machinery Co., prices of small excavators, Kerry and Heavy Industries (certified), Sichuan small excavators by 泰安嘉 and Heavy Machinery Co., Ltd ..
